Pray the Breastplate of St. Patrick against forces of the dark

When the forces of darkness are putting out their stuff, this breastplate acts like "the full armor of God..."

Saint Paul wrote:

“Put on the full armor of God, so that you can take your stand against the devil’s schemes. 12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. 13 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. 14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place…” – Ephesians 6:11-14

I arise today
Through a mighty strength, the invocation of the Trinity,
Through belief in the Threeness,
Through confession of the Oneness
of the Creator of creation.

I arise today
Through the strength of Christ’s birth with His baptism,
Through the strength of His crucifixion with His burial,
Through the strength of His resurrection with His ascension,
Through the strength of His descent for the judgment of doom.

I arise today
Through the strength of the love of cherubim,
In the obedience of angels,
In the service of archangels,
In the hope of resurrection to meet with reward,
In the prayers of patriarchs,
In the predictions of prophets,
In the preaching of apostles,
In the faith of confessors,
In the innocence of holy virgins,
In the deeds of righteous men.

I arise today, through
The strength of heaven,
The light of the sun,
The radiance of the moon,
The splendor of fire,
The speed of lightning,
The swiftness of wind,
The depth of the sea,
The stability of the earth,
The firmness of rock.

I summon today
All these powers between me and those evils,
Against every cruel and merciless power
that may oppose my body and soul,
Against incantations of false prophets,
Against black laws of pagandom,
Against false laws of heretics,
Against craft of idolatry,
Against spells of witches and smiths and wizards,
Against every knowledge that corrupts man’s body and soul;
Christ to shield me today
Against poison, against burning,
Against drowning, against wounding,
So that there may come to me an abundance of reward.

Christ with me,
Christ before me,
Christ behind me,
Christ in me,
Christ beneath me,
Christ above me,
Christ on my right,
Christ on my left,
Christ when I lie down,
Christ when I sit down,
Christ when I arise,
Christ in the heart of every man who thinks of me,
Christ in the mouth of everyone who speaks of me,
Christ in every eye that sees me,
Christ in every ear that hears me.

I arise today
Through a mighty strength, the invocation of the Trinity,
Through belief in the Threeness,
Through confession of the Oneness
of the Creator of creation.
